I have been on B12 injections for years, but since covid they don't last. I get mine every 8 weeks, but symptoms return after only one week now and get progressively worse, tremors, ataxia, severe pain in spine.... but GP refuses injections more frequently. How do I go about self injecting, where do I start, and how expensive is it? My local beautician can do it but it's $40.00 a pop.
I only get a state pension...
